Solana MC Breakout Sniper settings

Every setting the Solana MC Breakout Sniper's Expert settings can change, with the same names and help the Strategy page shows. The path is the setting's name in the bot's config file, which is what Raw config and harkctl config show. "Starts at" is a new bot's value (the Balanced starter).

You rarely need these. The Simple controls set most of them for you: Style sets its trigger and guards, how many tokens it holds at once, the protect-gains band and the time limit; Speed sets the priority fee and slippage; spend per token, take profit and stop loss set the buy size and the sell rules. Settings marked Advanced only appear only with the Advanced switch on. The Solana MC Breakout Sniper guide explains how the settings work together.

Ranges

Protect gains on the way down and Take profit on the way up are lists of ranges. Each range has a start and an end, a step, and the share sold at each step:

a protect-gains range is measured as the drop from the trade's peak: within the range it sells a share for each step down, and everything once the drop passes the end;
a take-profit range is measured as profit: within the range it sells a share for each step up. A range whose start equals its end is a single sell at that profit, and it still sells if the price jumps past it.

Set for you

These are part of the config but are set by AllenHark or elsewhere in the app, so they are read-only in Expert settings. The Solana Graduation, MC Breakout and Dip Snipers are one program run in three modes, so each config also carries the other two modes' sections, which this bot ignores.
